Abstract: The main objective was to evaluate various biological agents, as soil activators, which are used in the fall on the preceding crop (winter wheat) stubble and in spring on winter wheat at tillering stage, and the impact that these biological agents do to winter wheat seed crop development and productivity. Field experiment was conducted in 2014– 2015 at ASU Experimental Station. The soil type – Calc(ar)-Epihypogleyic Luvisols (LVg - pw - cc). After using Azofix (1 l ha-1) and Bactoforce (1 l ha-1) on the preceding crop stubble the wintering percentage was 84.7 % plants, while in the control group that was untreated the wintering percentage was 76 %. The use of biological preparations in the fall on preceding crop stubble and winter wheat in the spring at BBCH 30 stage had significant influence on crop density thinning during the vegetation progresses. The largest winter wheat grain yield (11.42 t ha-1) and the average head productivity (1.84 g) was set in the variant where plants where sprayed with both Azofix (1 l ha-1) and Bactoforce (1 l ha-1) combination in the fall and spring. Because of the biological preparations effects on winter wheat, yield structure elements (1.000 grain weight, number of grain in the head) had a tendency to increase
